渐消记忆滤波器在海上探雷试验中的应用

在海上进行探测水雷的试验中,常常因为船体的摇摆而使回波图像中目标的位置不固定,影响了水雷探测的准确性。研究基于Kalman滤波理论的渐消记忆递归最小二乘法,探讨渐消记忆递归最小二乘法在图像重建中的应用,并用于实现对回波图像的更新。结果表明,渐消记忆滤波器通过引入旧数据对图像更新的影响,使得回波图像中目标位置的变化具有连续性。

Application of Fading Memory Filter to Experiments Mine Detection on the Sea

When we experiment on mine detection on the sea it is always found that the position of target in echo images is not fixed because of sway of ship and this reduces the veracity of detection. The fading memory recursive least-squares based on Kalman filter is studied, and the fading memory recursive least-squares applied to rebuild images is also discussed in this paper, which is used for updating echo images. The results show that the fading memory filter makes the position of target in echo images continuous by introducing the influence of old data on image update.
